Describe the bug

The motif finding tutorial won't run, you can't download the data without the tutorial specific dependencies, which are in their own group in pyproject.toml but aren't defined as extras. This means tutorials work for me in development but don't work for PyPi installers - most users :/

To Reproduce

Steps to reproduce the behavior:

graphframes stackexchange stats.meta

Expected behavior

Users should be able to pip install graphframes[tutorials] and it will install dependencies like py7zr which we don't want to require in the main GraphFrames package.

System [please complete the following information]:

• OS: Mac OS X, late model
• Python Version: 3.12.9
• Spark / PySpark version: PySpark 3.5.4
• GraphFrames version: graphframes-0.10.0

Component
